For nineties glam girls with Gucci’s “Jackie” bag firmly strapped on their shoulders, the new Courrèges line (available exclusively at Jeffrey, $75-$1,500) is one more way to relive the former First Lady’s mod moment. The updated versions of the original designs will appease fans who until now have had to hunt for the architectural pieces at vintage shops. Madame Courrèges has put her own modern spin on her husband André’s signature looks from the Sputnik-chic era but retained his devotion to form over function: The breathtakingly brief minis, similar to the one in which Jackie sent shock waves at her wedding to Aristotle Onassis, come in plastic so stiff they could strut down the aisle by themselves.
